[G2 Q&A, Help & Troubleshooting] wabbisabbi:
Fail flash

Hey there. I'm not sure if this is the case with my phone yet, but I got him in a state that I really don't wanna mess up with even more than I've already did, so here is my story. Maybe I can get some better directions from now on, from an expert or someone that already went through this and recovered it's phone.

1. I got the phone as second hand from someone in Europe. Model D802, with KK 4.4.2 installed. Phone was working great, except for the WiFi signal which was horrendous and the modem which was very unstable (2 to 4 to 3 to 5 lines, like changing 2-3 times in a 10 seconds window). Phone calls seemed fine though.

2. The IMEI of the phone is 3xxx460xxx19700, which corresponds to a 32 GB D802 model (checked with various sites) - it was bought from Orange Romania.

3. The modem when I first got the phone was M8974A-AAAANAZM-1.0.190082, which corresponds to D803

4. I wanted to get rid of that strange WIFI and radio signal, so I thought to first update the phone to Lollipop (I was stupid, no serious research), which wasn't available as OTA. So I forced that through a .kdz flash, but for D802. Big mistake, because after that my touch screen started to behave heretical (touching a zone on the screen activates another area of it). Basicly, you can't do anything with the phone because it activates anything else BUT the zone you really touch. This is NOT the same problem as the one described in the thread below.

5. After further messing up with some different .kdz, I got it to an unknown baseband, imei, modem and firmware state. The phone was still fully functional, except for the touch problem. Also ween in device manager as G2, download mode working etc.

6. After that I did some serious research, opened my phone only to discover that it appears to be a D801 refurbished into a D802 - which I didn't know, of course. I panicked a little and started to gather some more info about the state of my phone.

7. Got on a long discussion with Murshad007, which provided me further directions for recovering my phone. I followed those thoroughly, and also checked with other sites that also gave the method of hex-modifying .tot flashing.

8. So I did as follows:

- Got the LGFlashTool for flashing .tot, LGD801_20130811_LGFLASHv160.dll, LGUP_8974.dll and overwritten MegaLock.dll in the LGFlashTool folder, as the instructions said.

- Got an HEX editor to modify the BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot. I changed D801 to D802, as instructed

- I loaded both the hex modified .tot and the LGD801_20130811_LGFLASHv160.dll. The LGFlashTool presented me the below error:

- Next, I did load the other .dll, LGUP_8974.dll, like it was written on the instructions (verified this with 3 sites)

- After that, the flashing started, but after the phone booted (93%), I got this error:

After a few more tens of seconds, tons of drives started to appear in My Computer, asking me to format each of them. I canceled all, power cycled my phone, and now I have a non-working download mode (it enters download mode but the phone isn't seen by the computer, nor is it seen by adb and fastboot) and a neverending pink logo :p

Any really expert advice is greatly welcome. I also consider giving a small donation for the one that helps me fix it.

Thanks.
